我们所栽种的许多作物,如茄子、辣椒、草莓、西瓜等,如果在同一块地上连作,就会发生土壤病害。但由于土地有限,连作情况难免出现。在这种情况下,要防治土壤病害,一个主要方法是进行土壤消毒。目前,由于药物消毒法成本高,残毒量大,难以推广。经我们多年摸索,利用太阳能进行土壤消毒,已取得了初步成功,现将方法介绍如下:1.具体方法(1)在气温较高的8～9月份,亩施厩肥1500～2000公斤,生石灰80～100公斤,全面翻耕作畦,畦宽1～1.2米,要求畦面平整。畦间留宽25～30厘米的沟,用于排灌水。(2)在畦上全面铺地膜,连续沟灌透水。3～5天后
Many of the crops we plant, such as eggplant, peppers, strawberries, watermelons, etc., can cause soil diseases if they are kept in the same lot. However, due to limited land, continuous production is inevitable. In this case, one of the main ways to combat soil diseases is to soil disinfect. At present, due to the high cost of drug disinfection, residual large amount of drugs, difficult to promote. After years of groping, the use of solar energy for soil disinfection, has achieved initial success, the method is described below: 1. Specific methods (1) in the high temperature of August to September, 1500 to 2000 kg of manure fertilizer, lime 80 ~ 100 kg, a full plowing for 畦, 畦 wide 1 ~ 1.2 meters, requiring 畦 surface formation.畦 left between the width of 25 to 30 cm ditch for irrigation and drainage. (2) Fully cover the membrane on the 畦, continuous ditch irrigation water. 3 to 5 days later
